The fastest way to change your desktop background

Right-click on any empty space on your desktop and select Personalize. Windows opens the Settings app to the Personalization section. Click Background in the left menu, then choose Picture, Solid color, or Slideshow from the dropdown at the top. If you pick Picture, click Browse to find an image file on your computer, or select one of the built-in Windows images from the gallery below.

The change takes effect when ready. Your new background appears on your desktop and lock screen unless you change them separately.

Key Takeaways

  • Right-click your desktop, select Personalize, then click Background to open the settings you need.
  • Windows 11 offers three background types: Picture (a single image), Solid color (one flat color), or Slideshow (multiple images that rotate).
  • You can use your own image files or choose from the built-in gallery that comes with Windows.
  • The lock screen background is separate from your desktop background and can be changed independently in the same Personalization menu.

Using a picture from your computer

If you have an image file saved on your computer, click Browse in the Background settings. A file browser window opens. Navigate to the folder where your image is stored — usually Pictures, Downloads, or Documents. Select the image and click Choose this image. Windows accepts JPG, PNG, BMP, and GIF files.

If you want to use multiple images and have them rotate, select Slideshow instead of Picture. Click Browse and select a folder containing several images. Windows will cycle through them at an interval you set — the default is 10 minutes, but you can change it to 1 minute, 10 minutes, 30 minutes, 1 hour, or 1 day.

Choosing a built-in Windows background

Windows 11 comes with a collection of images you can use without finding your own files. In the Background settings, with Picture selected, scroll down past the Browse button to see the gallery. Click any image to preview it. If you like it, click it again to set it as your background.

These built-in images are organized by category — landscapes, abstract designs, and others. You can scroll through the entire gallery to see what is available. The images are already on your computer, so they load when ready.

Setting a solid color background

Select Solid color from the dropdown at the top of the Background settings. A palette of preset colors appears. Click any color to use it when ready. If you want a color that is not in the preset palette, click Custom color at the bottom. A color picker opens where you can enter a specific hex code or RGB values, or click on a gradient to choose exactly the shade you want.

Solid color backgrounds use almost no system resources and load when ready. They are useful if you prefer a clean, minimal desktop or want to reduce the visual distraction while you work.

Changing your lock screen background separately

Your lock screen — the screen you see before you sign in — can have a different background than your desktop. In the Personalization settings, click Lock screen in the left menu. Select Picture from the dropdown, then click Browse to choose an image, or select one from the gallery below. The lock screen background updates independently of your desktop.

If you want both to match, set them to the same image. If you want them different, change one, then change the other.

Troubleshooting a background that will not change

If you click a new background and it does not appear, try closing and reopening the Settings app. Sometimes the display does not refresh when ready. If that does not work, restart your computer — this clears any temporary settings that may be stuck.

If you are trying to use an image file and the Browse button does not show it, make sure the file is in a location Windows can read, such as your Pictures or Documents folder. Files on external drives or network locations sometimes do not appear in the browser. Moving the image to your Pictures folder usually solves this. Also check that the file format is one Windows recognizes — JPG, PNG, BMP, or GIF.

Using a slideshow with multiple images

A slideshow rotates through a folder of images at a set interval. Select Slideshow from the Background dropdown. Click Browse and select the folder containing your images. Then set the interval — how often Windows switches to the next image. The options are 1 minute, 10 minutes, 30 minutes, 1 hour, or 1 day. Click the Change picture every dropdown to choose.

Windows cycles through the images in the order they appear in the folder. If you want to control the order, rename the files with numbers at the start — for example, 01-photo.jpg, 02-photo.jpg — so they sort the way you want. The slideshow continues even when your screen is locked, so you will see different images each time you wake your computer.

Frequently Asked Questions

Can I use a video as my desktop background?

Windows 11 does not support video files as a desktop background. You can use a still image, a solid color, or a slideshow of images. If you want moving visuals, a slideshow with a short interval between images is the closest option.

Where does Windows store the built-in backgrounds?

The built-in images are stored in a system folder on your computer, but you do not need to find them manually. The Background settings show them in the gallery, and you can select them directly from there. If you want to use one of these images elsewhere, you can find them in C:\Windows\Web\Wallpaper, but it is easier to just set them through Settings.

What image size works best for a desktop background?

Windows scales images to fit your screen, so any size works. However, images that match your screen resolution look sharpest. Most modern monitors are 1920 × 1080 or higher. If your image is smaller than your screen, Windows stretches it, which can make it look blurry. Larger images are scaled down, which does not affect quality as much.

Can I set different backgrounds for multiple monitors?

Windows 11 applies the same background to all connected monitors. You cannot set a different image for each monitor through the built-in settings. If you need different backgrounds on different monitors, third-party tools like DisplayFusion or Wallpaper Engine offer this feature, but they are not part of Windows.

Why does my background keep changing back to the default?

This usually happens if a Windows update runs or if your computer restarts unexpectedly. Make sure you have fully applied your background change before closing Settings — the change should take effect when ready on your desktop. If it keeps reverting, restart your computer and try setting it again. If the problem continues, check that your image file is not corrupted by trying a different image first.
